To all whom it may concern.' j

Be it `known that l, WILLIAM/F.r Harss'rrnN, ay citien ot' the United States, residing at Lyndhurgt, in the cgntnty of Bergen and State of New Jersey' iil'e linvented certain new,and useful lm )roven-lents in Calculatiiieh the Following is a specification.,

This invention relates to calculating machines such s that which forms the subjectmatter of EUSA. Patent $809,075, `granted to Alexander; Reehnilzer, January 8, 11H16.

In that imachine the various operations ol' u 'l 4 I addltion, subtraction, i-iniltlphention land division may be performed. flu ythe operi tion of nnlltiplication the figures of the uniltiplier to be used are set up by indicators or numeral slides in a series of graduated slots and the figures of. the multi plieand by a second series of numeral slides 1n a similar series ol slots, whilethe product is indicated on a series of numeral wheels which ma served through suitable sight holes.

The numeral slides which are used in multi licetionV to set upr the multiplier, and wliich, for the purposes of this specification, will be denominated multiplier slides, are also used in the operation ol division, in which case they are all lett atzvero at the be `ginning of the operation and the 'quotient is developed on them by the operation of the machine, the divisor being Set up by the other set of slides upon which the multiplicand is set up in multiplication, the dividend being indicated at the beginning on the numeral wheels.

In the operation of multiplimttion, it is necessary, in the machine ns now constructed, in order that an example may not be set up in which a product would be developed consisting of more digits than the immoral wheels would accommodate, that care be taken not to set u i a multiplicand and mul? tiplier which would produce such a result and for this reason it is advisable never to use a multiplier with as many digits as there are multiplier slides'. y'lhereore the lett hand multiplier slide should not be used.

The object of this invention is to absolutely prevent 'the operator from so doing, and with this .object in view the inventionl consists in n'oviding means whereby the lett hand multiplir-n' slide will he rigidly locked in the aero` position when the machineA is other y be obl wise in condition to vstart au operation of r multiplying.

In the accompanying drawing. in which I vhave illustrated my invention in connection with so much ol the original machine as is necessary to a )roper understanding of its construction ant operation, Figure 1 is a bottom plan view, parts being broken away. Fig. is a top plan View, with the top plates ol the machine removed, said top plates be, y ing indicated in dotted lines and other parts being broken away', and Fig. 3 is a transverse yseetioiml View. r e

`Referring specifically to the drawing, it may be stated that the maehinereferred to comprises multiplier slides to the number ot' nine, oi which the numerals 1Q, 18, 17, 16 and 15 ind ieate those. of the multiplier slides to the lelt. ot the series (the others being broken away). These are illustrated as fitted to slide in corresponding graduated slots 29, 28, 27, 26, 25, formed in the top plate 4 of the sliding carriage of the machine. To each of these slides isvattachedv one of the racks 39, 38, 37, 3G, 35, which serve to connect with the calci-dating mechanism (not shown). The top plate of the stationary portion of the machine is indicated atA 5 and all of the multiplier slides are shown inthe zero position, with the carriage in the position which it is necessary for it to occupy aft the lbeginning' of the operation ofmultiplication.

i' In suitable bearings (not shown) in the 'stationary portion ol' thek machine is mounted a slidabie rock shaft 6 on' which `is secured a starting lever Ffwh'ich passes upward through a slot 8 in the top plate 5 of the stationary part, said lever being moved'to various positions in the slot 8 in order to startthe mawhich itl is capable.

'lo any suitable part of the stationary portion of the machine, in this instance to a plate t) is secured a spring awl 10 which., when the carriage is in .position for starting the operation of multiplication, is in line with the numeral slide 19 at the left of the/series. This pawl is so constructed and placed that when the carriage is in this position, and that numeral slide is moved to the Zero position, as shown in the drawing, said ia-wl will spring into position behind that slide and securely lor-l( it against any attempt to move it out of .such/1ero position.

chine to perform the several operations of lee Should the. operator carelessly start to set up a multi lier which contains as many digits as t ere are Vmulti lier slides and graduated slots, he will t ius be sto ped when he reaches this slide and attemps to move it out oi the zero position, thus warning him that his problem cannot he worked on this machine.

As soon as an operation within the capacity of the machine is started, the carriage will slide out of the position illustrated. This will also be lthe case when a roper operation in division is started,- so t at during the latter operation, the locked slide will be released from the pawl and may move in develo ing the quotient as before described.

` at I claim as new is 1. In a machine of the character described, the combination with the stationary portion thereof, of a slidable carriage having slots, a series of slides carried thereby in said slots, and means for locking the left hand slide in its normal position when the carriage is in its normal position. l

2. In a machine of the character described, the combination with the stationary portion thereof, of a slidable carriage having slots, a series of slides carried thereby in said slots, and means carried by the stationary portion for locking the left hand slide in its' normal position when the carriage is in its nor'r/nalI position.

In a machine ofthe character described, the combination with/the stationary portion thereof, of a slidable carriage-having slots, a series of slidesv carried thereby, in said slots, and a pawl for locking the left hand slide in its normal position when the carriage is in.its normal position.

4. In a machine of the character described, the combination with the stationary portion thereof, of a slidable carriage having slot-s, a series of slides carried thereby in said slots,

the combination with' the static and a pawl carried by the stationary portion ss2,ssv

for locking the left hand slide in normal position when the tion.

5. In amachine of the character described, portion thereof, of a slidable carriage. havin slots, slides carried thereb in said slots, an means for loc theleft hd slide in its normal position w en the carriage is in its normal poin-its normal posi- Y sition and releasing the same when the car- V riage is moved out of its normal position.

6. In a machine of the character described, thecombination with the statioharyfportion thereof, of a slidable carriage ha'vin'glslots, a

A n testimony whereof I affix my signature in presence of two witnesses.'
